Quality Grading
Grading Colorless Diamonds
In order to assess the value of a diamond, laboratories have created a grading system used internationally since the 1950’s. This system is based on the well known 4 Cs, which are used to grade all diamonds, whether colorless or colored.
Everyone has heard about the 4 Cs, also known as Carat, Color, Clarity, and Cut. They are classified in descending order of importance, Carat being the most important one. Learn about the history of this grading system and how it is used to assess the quality of a colorless diamond.
